Built in-house by U.S. Navy SEAL Team armorers, and later by the Naval Surface Warfare Center, Crane Division (often referred to as NSWC-Crane or "Crane"), the SEAL Recon Rifle was developed to provide SEAL snipers with a portable, lightweight system with greater lethality than a standard M4 carbine. The SEAL Recon Rifle is sometimes referred to as the "Recce Rifle".
